The buildbot printed "expr: syntax error", presumably from this, but
that oh-so-descriptive error message doesn't indicate what the problem
is, and just about any string should be valid as the left-hand operand
of the : operator.

Add a script that takes a command as an argument and runs it in a
subshell, so that said subshell will catch any signals from it and
report it.
This would be done for commands that aren't the last command in the
pipeline, as, given that the exit status of a pipeline is the exit
status of the last command in the pipeline, there's no guarantee that
the shell will bother to pick up the exit status of earlier commands in
the pipeline.
Use that for the tshark in the WPA EAPOL Rekey test, so it at least can
report the signal (on Solaris, SIGSEGV means, among other things,
"dereferenced a pointer pointing out of the address space" and SIGBUS
means, among other things, "dereferenced a misaligned pointer on
SPARC"). Maybe we can make the script also fire up a debugger if it
finds a core dump (and a debugger) and get a stack trace.
